When is parking considered a violation?

Parking is considered a violation at the entrance and exit of hospitals and fire stations primarily due to the need for quick access for emergency services. These areas are critical for the safety and efficiency of emergency responders. If a vehicle is parked in these locations, it can obstruct ambulances or fire trucks from entering or exiting swiftly, which can have serious consequences in emergency situations.

The other choices suggest scenarios where parking might be highly discouraged or regulated, such as in front of schools during specific hours or in no-parking zones. However, the urgency of maintaining clear access at hospitals and fire stations makes it particularly important to avoid parking in these areas to ensure public safety is upheld.
